Abstract
A secure multiple application card system and process is provided having secure loading and deleting capability by use of a Certification Authority and Personalization Bureau. The certification authority maintains the security of the system by requiring IC cards to be injected with its public key and a card identifier for uniquely identifying each card, by providing a personalization data block for each card, and by signing with its private key all applications to be loaded or deleted from the IC card.
Claims2
A method for securely loading an application onto at least one integrated circuit (IC) card, comprising:
- a first step of determining, based at least upon an encrypted personalization data block, whether the at least one IC card is part of a qualified set of IC cards to accept loading of said application;
- and
- a second step of loading the application onto the IC card only if the first step determines that the IC card is qualified to accept the loading of the application.
A method for securely deleting an application from at least one integrated circuit (IC) card, comprising:
- a first step of determining, based at least upon an encrypted personalization data block, whether the at least one IC card is part of a qualified set of IC cards to accept deleting of said application;
- and
- a second step of deleting the application from the IC card only if the first step determines that the IC card is qualified to accept the deleting of the application.
